The rate determining step is surface reaction between adsorbed molecules of methyl acetate and unadsorbed molecules of water ( single site mechanism ). 结果表明反应过程控制步骤是吸附在催化剂表面的醋酸甲酯同未吸附的水发生表面反应。
The results of kinetic investigation showed that the main rate determining step was diffusion control of liquid film. 动力学研究结果表明,树脂与游离脂肪酸的离子交换过程的主控速步骤是液膜扩散控制。
The dissolving of the organic film with intermediate products on the anode is the rate determining step. 由中间产物构成的有机膜的阳极溶解是反应的慢步骤。
The results also showed that the photodegradation rate of endosulfan was faster than the elution rate from soil, and the surfactant elution was the rate determining step in the whole process. 研究发现,硫丹的光催化降解速率明显快于表面活性剂洗脱土壤中硫丹的速率,降解速率和程度取决于表面活性剂对硫丹的洗脱速率和程度。
The photodegradation process could be well described by a four-parameter biphasic first-order reaction kinetic model, and showed obvious rapid and slow photodegradation phases, the latter was the rate determining step. 4参数2室一级反应动力学模型可以很好地描述同时洗脱和光催化降解土壤中硫丹的过程,包括快速光降解和慢速光降解两个阶段,后者是整个降解过程的速度控制步骤。
